All is silent: from the essayist Gui Youguang's "Xuanzhi of Mountain Ridge";

"The bookshelf is full of books, singing stiffly, sitting silently, and everything is audio. But the footsteps are silent, birds peck, and people don't leave. On the fifth night of March, half of the month, the laurel shadow is mottled, the wind is moving, and it is lovely. "
